Abstract

Abstract Transverse arrangement is one of the main methods used in the polar inertial navigation system (INS). In the traditional algorithm, the calculation of using the earth ellipsoid model is complex, while using the earth sphere model cannot satisfy a high-accuracy application. Therefore, an approach based on the virtual sphere model is proposed, which has been proved in simulation experiments to reduce the computational complexity and maintain the same accuracy as the ellipsoid algorithm, but its accuracy has not yet been proved in theory. Starting from the basic principles of the ellipsoid and virtual sphere model algorithm, this paper compares the key formulations of the two. Finally, it is proved that the two arrangements are actually the same.

横向布置惯性导航系统中椭球和虚球模型的分析与讨论

摘要横向排列是极坐标惯性导航系统的主要方法之一。在传统算法中，使用地球椭球模型计算复杂，而使用地球球体模型无法满足高精度的应用。因此，提出了一种基于虚拟球体模型的方法，该方法在降低计算复杂度的同时保持了与椭球体算法相同的精度，但其精度在理论上尚未得到证实。本文从椭球和虚球模型算法的基本原理出发，对两者的关键公式进行了比较。最后，证明了这两种排列实际上是相同的。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
